1-2. Component Operation
a. Motor/Pump Operation
The motor/pump assembly is a gear type pump
that provides the oil pressure and volume for the
entire hydraulic system. The pump has an inlet
side and an outlet side. The inlet side is connected
to the reservoir which provides the oil supply . The
reservoir has a very fine mesh screen strainer
which prevents foreign material from entering the
oil system.
The output line of the pump is connected to the
main oil galley which is internal and common to all
the hydraulic mini-valves and pressure relief valve.
Also, common to the hydraulic mini-valves and
pressure relief valve is an oil galley that internally
connects to the oil reservoir to provide a return
path for the hydraulic oil. See figure 1-2.
Turning the adjustment nut clockwise increases
the amount of oil pressure required to open the
valve, and turning it counterclockwise decreases
the amount of oil pressure. (See adjustment section for specification.)

b. Pressure Relief Valve
This device provides an alternate oil path when
the hydraulic cylinders reach the end of their stroke
and the pump continues to run. If this path were
not provided, the pump motor would stall because
the oil cannot be compressed. The pressure relief
valve is directly connected to the mini-valve bodies and shares both the common internal main
pressure oil galley, and the return oil galley, that
internally connect to the reservoir. See figure 1-3.

The main component of the valve is an adjustab le

Figure 1-4. Pressure Relief Valve Functioning
c. Mini-Valves
The operation of the mini-valves is identical for all
table functions except the ele v ation and br ak e circuits. These two hydraulic circuits use a 3-way
(single check valve) type mini-v alve. All other functions use a 4-way (dual check valve) type minivalve.
Either type mini-valve is controlled by two pushing
type, electrically operated solenoids. The solenoids
push the spool valve (located in the lower portion
of the valve) one way or the other. This motion
opens the main supply galley (which has pump
pressure) allowing the oil to flow through the various parts of the mini-valve to the function. The
spool valve also opens an oil return circuit which
allows the oil to return to the oil reservoir.
The main components of the mini-valve and their
functions are listed below:
1. Spool Valve - Opens the main oil galley
(pump pressure) to either mini-valve outlet depending on which direction the spool valve is pushed.
Also it provides a return path for the oil returning
back into the reservoir.
2. Pilot Plunger - There are two plungers in a
four-way mini-valve (one in a 3-way mini-valve),
one under each check valv e. The purpose of the
pilot plungers is to mechanically open the return
check valve allowing the oil to return back into the
reservoir.
The speed controls are always located in the return oil circuit. This prevents uncontrolled movement of the piston in the slave cylinder due to one
side of the piston being loaded with hydraulic pressure and the other side having no load.
Also, by using this control method, it doesn’t matter
what size cylinder and piston is used because the
speed can be controlled by restricting the return oil.
If the pump puts out more volume to a certain slave
cylinder than the speed control is allowing to go back
to the reservoir, the pressure relief valve provides
an alternate path for the pump oil.
d. Mini-Valve in Neutral Position
(No fluid flow) See figure 1-5.
1. Spool V alv e Centered - This closes off both
oil pressure and oil return galleys.
2. Pilot Plungers Both Closed -The pilot plungers control the opening of the check valves. If they
are closed, the check valves must be closed.
3. Check Valves - Both check valves are
closed trapping the oil in the cylinder and oil lines.
4. Speed Adjustment - When the mini-valve
is in the neutral position, the speed adjustment
does not affect anything because there is not any
oil flow.
3. Check Valve - Two are provided in each
four-way mini-valve to seal the oil in the cylinders
and oil lines and prevent any movement of the
table. One check valv e is provided in a 3-wa y minivalve.
4. Speed Adjustments - There are two speed
adjustments in each mini-valve. They are needle
valve type controls which restrict the volume of oil
returning back into the reservoir, thereby controlling the speed of the table surface movement. A
3-way mini-valve has only one speed adjustment.

and on to the cylinder. Also , the spool valve opens
the oil return line providing an oil path through the
internal oil galley back to the reservoir.
2. Pilot Plunger V alv e - Left pilot plunger valv e

the return circuit. This action allows the oil from
the left side of the slave cylinder to go back into
the reservoir. The right pilot plunger valve is not
affected in this operation mode.

3. Check Valves - Both check valves are
opened in this operation mode. The right check
valve is pushed open by the oil pressure created
by the pump. The oil then continues to go through
the lines and pushes the slave cylinder piston to
the left. At the same time, the left check valve is
held open mechanically by the pilot plunger providing a return path for the oil through the minivalve back to the reservoir.
4. Speed Adjustment - The right speed control (output side) does not have any effect in this
operation mode because the oil is routed around
the speed adjustment through a by-pass valv e and
then to the output port. The left speed adjustment
controls the speed of the table function by restricting the amount of oil going back into the reservoir.

There are several different types of hydraulic cylinders used in the table that activate the control
functions. With the exception of the elevation and
brake cylinders, all oper ate basically the same way .
The control functions are:
Reverse Trendelenburg/Trendelenburg
Lateral Tilt
Elevation
Brake Cylinders
Longitudinal Slide Function - 3001 Only
Lateral Slide Function - 3001 Only
1. Trendelenburg Cylinder - The double
action cylinders are closed at one end and have a
movable piston with hydraulic fluid on both sides.
Connected to this piston is a ram or shaft that exits
out of the other end of the cylinder. Through the use
of a ball and socket arrangement this ram is
connected to a movable table surface.
The movable surface can be moved one way or
the other by pumping hydraulic fluid into the cylinder on either side of the piston. Obviously, if oil is
pumped into one side of the cylinder, a return path
must be provided for the oil on the other side. See
figure 1-8.
TRENDELENBURG
CYLINDER
The pistons and connection rods are attached to a
non-movable surface. Therefore, when hydraulic
fluid is pumped into one side, the cylinder housing
itself moves around its pivot pin causing the table
top to tilt to one side. To tilt the table top in the
opposite direction, hydraulic fluid is pumped into
the other side of the cylinder assembly.
Figure 1-9. Lateral Tilt Cylinder Assembly
3. Longitudinal Slide Cylinder Assembly - 3001
Only - The longitudinal slide system utilizes two
double action cylinders working in tandem. The
two cylinder housings are connected together facing opposite directions. The ram of one cylinder is
connected to the table top frame and the other one
is attached to the elevation column. Hydraulic fluid
is pumped into the same end of both cylinders at
the same time. The two cylinder system allows
the 20" of top slide to be performed by a short
cylinder system. See figure 1-10.
with two pistons complete with connecting rods.
The connecting rods are attached to a stationary
pin in the housing on top of the main support column. The cylinder housing attaches to the table
frame and is attached to the support column with

This cylinder is also a double action cylinder. It
differs from the Trendelenburg cylinder in that the
piston is connected to rams which exit from each
end of the cylinder tube. The ends of the rams
connect to each side of the table top . The cylinder
tube is connected to the elevation column. When
hydraulic fluid is pumped into one side of the cylinder, the entire tab le top assembly will slide laterally. See figure 1-11.

5. Elevation Cylinder - This single action cylinder does not have hydraulic fluid on both sides
of the piston. It depends on the w eight of the tab le
top assembly to lower it.
The cylinder is set in the center of the elevation
main column. The piston and piston rod are elevated by the driven force of the oil pressure.
When lowering, the oil that is accumulated in the
cylinder is returned to the oil reservoir through the
mini-valve due to the table top weight.
A slider support assembly is used to support the
weight of the upper table section. A stainless steel
shroud covers the flexible hydraulic hoses and
slider. See figure 1-12.
Figure 1-12. Elevation Cylinder Assembly
6. Brake Cylinders - The brake cylinders are
single action type similar to the elevation cylinder.
The movable piston ram is connected to a brake
pad. See figure 1-13. Oil pumped into the top of
the cylinder pushes the piston down raising the
table base off its casters. An internal return spring
pushes the piston up to return the oil through the
mini-valve to the reservoir.

h. Elevation Cylinder Return Circuit
i. Brake System
A three-way (single check valve type) mini-valve
controls both the elevation and return circuits. The
elevation circuit operation within the mini-valve is
identical to the operation of the four-way valves
previously described (inlet pressure opens the
check valve allowing the oil to enter the cylinder).
In the return position, inlet pressure pushes the
pilot plunger up and opens the return check valve.
See figure 1-16. The open check valve allows a
path for the oil in the ele vation cylinder to return to
the reservoir. When the pilot plunger valve is
opened, the continuing pump pressure opens the
pressure relief valve which provides a return oil
path to the reservoir.
The mini-valve used in the elevation circuit contains only one check valv e (all four-way mini-v alves
use two check valv es). The check v alve is used to
trap the oil in the elevation cylinder thereby supporting the table top. When the top is being lowered the check valve is mechanically held open by
the pilot plunger through pump pressure.
The brake system consists of the following components: (figure 1-17)
1. Single action slave cylinders (4 each).
2. 3-way (single check valve type) mini-valve.
3. Manually controlled emergency brake re-
lease.
4. Plumbing terminal, flexible hoses, copper
lines and "O" rings.
5. Portions of the electrical system.

Each corner of the cast-iron table base has a hydraulic brake cylinder. These single action cylinders are hydraulically connected in parallel to the
mini-valve and all f our are activ ated together. It is
normal for one corner of the table to raise before
the others due to the weight distribution of the table.
An electronic timer in the relay box is activated
when any function on the pendant control is
pushed momentarily . The pump/motor and brake
system mini-valve are activated and the brake cylinders are completely set. The electronic timer
runs for approx. 8-10 seconds.

The brakes are released by pushing the BRAKE
UNLOCK button momentarily. An electronic timer
in the relay box activates the brake function hydraulic mini-valve and pump/motor.
1-3. Hydraulic Adjustments
a. Fluid Level.
When activated, the return hydraulic circuit operates similar to the elevation cylinder return circuit.
Return springs inside the single action brake cylinders retract the brake pads and provide the pressure to return the hydraulic oil back to the reservoir. The electronic timer operates the return circuit for approximately 8-10 seconds.
j. Emergency Brake Release
The emergency brake release is simply a manually operated bypass valve connected in parallel
to the brake cylinders and the oil reservoir. See
figure 1-18. When the valve is opened (turned
counter-clockwise) a return circuit for the brake
hydraulic fluid is opened. The return springs force
the pistons up pushing the hydraulic oil back into
the reservoir and retracting the brake pads.
The fluid level should be approximately 1/2" below
the filler hole or gasket surface. If additional fluid
is needed, remove the filler vent cap with a phillips
screwdriver and add fluid through this opening
using a funnel. See figure 1-19.
NOTE
The elevation cylinder should be completely down, the brakes released and
all the other control functions in their
neutral position when checking oil level.

NOTE
•The emergency brake release valve
must be tightened securely when not in
use.
•If the emergency brake release valve
has been operated, the BRAKE UNLOCK button on the pendant control
may have to be pressed before brakes
will lock again.
If the emergency brake release valve is open or
loose, the brakes will release slowly- depending
on how loose the valve is, this could take anywhere from a few minutes to several hours.
Figure 1-19.
The type of oil that should be used is Mobil DTE
#25 or equivalent. This is a very high quality hydraulic oil. The table requires approximately two
quarts of oil to operate properly. Exercise caution
when determining equivalence to avoid damage
to the hydraulic system.
b. Bleeding The Hydraulic System
To purge the air from the hydraulic system, operate each function back and forth at least two or
three times.
NOTE
Whenever a hydraulic line or component is replaced, bleed the air out of the
lines using the pump pressure before
making the final connection. Then operate the function until it stalls in both
directions.
